The net present value (NPV) and internal rate of return (IRR) methods of investment analysis are interrelated and are sometimes used together to make capital budgeting decisions. Consider the case of Green Caterpillar Garden Supplies Inc.: Last Tuesday, Green Caterpillar Garden Supplies Inc. lost a portion of its planning and financial data when both its main and its backup servers crashed. The company's CFO remembers that the internal rate of return (IRR) of Project Gamma is 13.8%, but he can't recall how much Green Caterpillar originally invested in the project nor the project's net present value (NPV). However, he found a note that detailed the annual net cash flows expected to be generated by Project Gamma. They are: Year Cash Flow Year 1 $1,800,000 Year 2 $3,375,000 Year 3 $3,375,000 Year 4 $3,375,000
